IMPROVEMENT IN MACHINES FOR CUTTING SHOE-WELTS.

Specification forming part of Letters Patent No. 126,673, dated May 14,1872.

To all whom it may concern:

Be it known that I, J AMEs H. BUsELL, of Boston, in the county of Suffolk and State of Massachusetts, have invented an Improvement in Outting Shoe-Welts; and Ido hereby declare that the following, taken in connection with the drawing which accompanies and forms part of this specification, is a description of my invention sufficient to enable those skilled in the art to practice it.

In making edge-welts for boots and shoes it is customary to use one strip extending around or angles are usually cut by hand, and are not very-quickly nor perfectly formed.-

My invention relates to a means of simultaneously cutting both notches by a knife-cutter or die, which is made with two pairs of angling blades, the edges being so shaped and so disposed relatively that at one blow of the cutter both notches are formed. This double and an gle-edged knife or cutter I attach to a head-piece on the upper end of a vertical rod or shaft which is mounted in avert-ical sleeve, in which sleeve it is made capable of free. vertical movements, the stress of a suitable spring forcing the rod and cutter-attached head up, and they being thrown down by action of a treadle-lever. The cutter projects over or overhangs a cutter-block, with the top surface of which the planeof the cutting-edge is parallel, and at the back of this block is an edgegauge against which the thick edge of the welt-strip is held. It is in a machine having this general construction that my invention consists. r

The drawing represents a machine embodying my invention.

A shows a plan of the machine; B, a section on the line at w. 0 shows the machine in a perspective elevation.

to denotes a strong metal stand, at the front part of which is a block-receiving space for containing the cutter-block b, which block has ahorizontal cutting-face, 0. Behind this block is a vertical sleeve, d, in which slides a piston or shaft, 6, having fixed upon its upper end a head, j, which overhangs the block and has fixed to it the cutter-blade g. This blade is secured to the head by screws h, or other suitable fastenin gs, and has two A-shaped cuttin gedges, between which is an open space, 6, these edges or their cutting-plane being parallel to the upper surface a of the block b. At the back of the block b is an edge-gauge, k, made adjustable in position by a screw, 1, and slot m, or other devices, the gauge being the surface against which the back of the welt is held, to determine the distance from the back or thick edge of the welt at which the knife shall cut the notches. n denotes the spring that forces up the cutter, and to draw it down the bottom of the shaft may be connected with a treadle-lever, the bed-frame a being set upon a bench and the treadle connection being beneath the bench. l) denotes the welt, showing the form and position of the notches 0 o, the two notches being simultaneously cut by the descent of the cutter to the top of the block, as will be readily understood. By these means the welts are rapidly and very perfectly notched for bending into form.

I claim- The cutter g, made with the two notch-formin g edges, the cutter being attached to the overhanging head f, and having vertical movements imparted to it to carry it down to and up from the block b, substantially as described.

Executed this 15th day of February, A. D. 1872.
